When trying to find free online invoicing software, it can often be difficult to find ones that are truly free, with no “catches” that you don't realize are there until far too late. Too many of these “free” pieces of software turn out to be free trials, or have certain limitations that you will easily exceed as your business grows. Thankfully, we've found some online invoicing software that actually lives up to their low-budget advertising.
InvoiceBubble – The 100% Free Ad-Supported Option
InvoiceBubble is perhaps the most popular free online invoicing software that is available right now, and is able to create very professional looking invoices for businesses that are just starting out. Of course, you don't have to be a business to have a need to send invoices out, and InvoiceBubble also works great for any independent contractor, like a freelancer. There is no limitation on the free version of InvoiceBubble, but you can pay a flat fee to get rid of ads if you like, but it doesn't change functionality at all. This service even allows for PayPal payments for retailers who prefer to take Paypal, or sell through eBay.
